To all whmn it may concern:

.Be it known that I, OLIVER NOLAN, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Brick-Machines, of which the following is a specification.

My invention is an improvement inbrickmachines; and it consists in certain novel constructions and .combinations of parts hereinafter described and claimed.

Referring to the drawings formin a part hereof, Figure 1 is a top plan view 0 my imroved machine. Fig. 2 is an end elevation. ig. 3 is a detail of one of the partition-plates.

' Fig. 4 is a bottom ptlan view, and Fig. 5 is a vertical section on e line 5 5 of Fig. 1. Fig. 6 is a perspective view of my improved machine, showing its position when the brick are removed; and Fig. 7 is a detail of the camshaft for starting the brick.

In the practical application of my invention I provide a base A, comprising two airs of longitudinal stringers ,a, a, 0. an (1 spaced apart and connected at their ends'by cross-bars a a which extend beyond the forward pair of stringers. A horizontal plate a, restsupon the rear pair of stringers and is provided with a series of s aced grooves a on its inner edge. A secon horizontal plate a rests upon the outer strin er-of the forward air and upon the exten ed ends of the crossars, and a vertical plate a, is. secured" to the inner edge of the horizontal plate. A series of grooves a is provided on the inner face of the vertical plate corresponding in position to the grooves on the inneredge of the rear horizontal plate, and a series of braces a, resting upon the forward horizontal plate,

is connected to the vertical plate between the grooves.

A series of partition-plates grooves of the rear horizontal plate and the upright plate and upon the upper edgeof the inner stringer of the forwar pair, and each late is provided with an o ening b in the ower edge thereof, A lon itudinal-bar. I), provided with erforations If correspondin in. position to t e partition-plates, is secure to the inner face of the inner stringer of the forward pair. Screw-threaded bolts I), having hooks 'b" to engage the openings in the partition-plate, extend downward through E rests in the the perforations in the longitudinal bar and are secured thereto by nuts A frame 0 is connected to the rear horizontal plate by hinges c, and secured to the inner edge thereof is a vertical plate 0, provided on its inner'face with a series of grooves c to receive thefree ends of the partition-plates. Braces a rest upon the hinged horizontal plate and are connected to the vertical plate etween the moves. -U on the lower face of the hingedIi ries of fingers c of a length and'width corresponding to the distance between the vertical lates and to the distance between the partitionlates, respectively. The abovedescribed gers are adapted when in their. closed position to rest upon the upper edge of the inner stringer of the forward pairand to close the lower part of the opening between the artition-plates, thus forming a series of mol s D, closed at-the'ends by the vertical p1ates,'at thesides by the partition-plates, and at the bottom by the fing'ers.

Secured to the ends of the frame are handles E for convenience in turning the same upon its hinges.

In practical operation when a series of ten brick are tamped in the molds, it has been found difficult to move them, and the following mechanism is provided for that purpose.

A shaft F, provided with a series of cam-fingers f, corresponding in number to the number of molds, is journaled in the ends of the frame, the fin ers being adapted when the shaft is rotate to engage the bottom of the mold to aid in starting the brick. For conveniencefin'manipulatingthe shaft a handle or crank f is provided. When the shaft is rotated, the, fingers engage the movable bottoms, affording a powerful leverage for starting/{the bricks. V

y invention is especially adapted for making concrete brick, but may be used for "making brick of clay or other material.

In operation the material is laced in the molds and tamped therein. A card is then z-laid aoross the tops of the molds, the ends of the board resting upon the handles E. The

. swinging frame is 'then turned backward with the board, and since the position of the brick is reversed the board will be underneath, and when the bottoms are turned back ilpto-gosition the brick will remain upon the oar orizontal p ate is secured a seeasily operated. I It is also self-cleaning, the

bottoms of themolds performing this func-- tion.

When it is desired to make colored brick, the coloring-matter may be placed in the bottom of the mold.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a brick-machine, the combination of a base, comprising pairs of longitudinal stringers spaced apart, cross-bars connecting the ends of the stringers, a horizontal plate resting upon the rear pair of stringers, and provided with a series of spaced grooves on its inner edge, a horizontal plate resting upon the outer stringer of the forward pair, a vertical plate secured to the inner edge of the horizontal plate, and provided with grooves on its inner face corresponding to the grooves on the rear horizontal plate, braces'resting on the forward horizontal plate and connected with the vertical plate between the grooves, partition-plates having openings in their lower edges resting in the. grooves of the vertical and rear horizontal plates and upon the inner stringer of the forward pair, a longitudinal bar-secured to the inner face of the inner stringer of the front pair and provided with perforations, screw-threaded bolts provided with hooks for engaging the open- 'ings in the partition-plates, and extending to the perforations in the longitudinal bar, nuts ,engaging the bolts, a swinging frame hinged to the rear horizontalplate, and comprising a horizontal plate, a vertical plate secured to *the free edge of the horizontal plate and provided with grooves. to receive the free edges of the partition-plates, braces resting on the.

horizontal plate and connected to the vertical plate between the grooves, a plate secured to the lower face of the frame extending across the space between the vertical plates, and provided with openings to receive the partitionplates, and handles secured to either end of the frame at the level of the top of the partition-plates.

i 2. In a brick-machine, the combination of a base, comprising pairs of longitudinal stringers spaced apart, cross-bars connecting the ends of the stringers, a horizontal plate restin upon the rear pair of stringers and provided with a series of spaced grooves on its inner edge, a horizontal plate resting upon the outer stringer of the forward pair, a vertical plate secured to the inner edge of the horizontal plate and provided with grooves on its inner face corresponding to the'grooves on the rear horizontal plate, braces secured to the outer face of the vertical plate between the grooves, partition-plates resting in the grooves of the vertical plate and the rear horizontal plates and upon the inner stringer of the forward pair, a longitudinal bar secured to the inner face of the inner-stringer of the front pair, means for securing the partition-plates to the bar, a frame hinged'to the rear horizontal plate, and comprising horizontal and vertical plates, a vertical plate having grooves on its inner face to receive the free edges of the partition-plates, a series of braces between the horizontal and vertical plates, a series of fingers secured to the frame and adapted to close the lower openings be tween the partition-plates, and handles secured to eitherend of the frame at a level with the to of the artition-plates.
